A steep staircase descends to Tomb 1 with its stucco decorations depicting owls and cat-motifs and bas-reliefs of a person whose torso is covered with a turtle shell and another figure whose head is shown emerging from a serpent.

During growth these relative proportions change in a most noticeable way; thus, for example, in the adult the torso is fully half of the entire stature and, according to the individual, corresponds to 51 or 52 per cent of it.
